The Great New York 100

Founded in 2012 by race director Phil McCarthy, The Great New York 100 runs 100.3 miles through four NYC boroughs — starting and finishing in Times Square, north through Manhattan, the Bronx, Queens, Brooklyn, and back via the Brooklyn Bridge. The course is predominantly pavement with roughly 3 miles of trail in Van Cortlandt Park; bridges supply most of the ~3,000 feet of elevation. A 30-hour cutoff governs the 100-miler; pacers are allowed from mile 32. No closed streets or course markings in most sections — runners navigate with GPX files and buy food at bodegas along the way.
